Samsung didn't mention pricing or availability for the REX line, but the company plans to offer these phones in emerging markets with low price points

Samsung announced a new series of smart feature phones called REX, which consists of four available models.

The REX series offers four new phones, including the REX 60, REX 70, REX 80 and REX 90. All four come with an intuitive, touchscreen user interface, a compact design and an optional Dual SIM for those who want to separate their work lives from personal lives.

“As the number one mobile leader and innovator, we are committed to developing the best possible mobile solutions to suit all lifestyles and budgets, which is why we are so excited to launch the REX series across a number of the world’s fastest growing markets,” said JK Shin, President and Head of IT & Mobile Communications Division at Samsung Electronics. “REX devices are designed to seamlessly prioritize and consolidate essential mobile functions that matter most to customers across diverse markets. The result is an extraordinary end-to-end mobile experience with the best value for money.”

Samsung didn't mention pricing or availability for the REX line, but the company plans to offer these phones in emerging markets with low price points.

My Lumia 620 (which is a massively under rated phone in my opinion) gets over 8 days normal use if you put "battery saver mode" on, and all that really means is your emails don't get automatically synced.
